comment Surprise exam paradox?
I don't quite understand why the knowledge gets represented as a partition of the states of the world. Isn't it possible that in one situation we know the world is in state A or B and in another we know it is in A or C?

comment A challenge by R. P. Feynman: give counter-intuitive theorems that can be translated into everyday language
If the question is written as, "We search until we find a parent who has two children with one a boy born on a Tuesday and the other is not a boy born on a Tuesday", then it's much more obvious what is going on

comment Function to create a smooth, monotonically non-decreasing curve between three points
@DavidH: That's a nice solution for the simple problem. Now if only there was a way to get the gradient to 0 at the end (in some cases the gradient might be heading towards minus infinity instead of 0)

comment Function to create a smooth, monotonically non-decreasing curve between three points
@Bitrex: Sure. It would be nice if it weren't just smooth in terms of gradient - but had continuous higher order derivatives too, but I won't say that that is strictly necessary
